MIdrum UC33

MIdrum is a rythmmachine outputting midi. A good explanation of the generative principle kan be found in the Manual of Grids.

Just to be absolutely clear: the idea of generative eigendrums is not mine.
I just thankfully use ideas and code by Olivier Gillet of Mutable Instruments.

Left
This version has 6 drum-channels.
The fader sets the Density for a channel (BD), the pot above adds to that a random amount.
The middle row pot scales the velocity for the channel. The top pot selects the midi note number.

The first 3 channels are the same as those in Grids.
The second 3 channels are derived from the first 3 by calculating their density based on the density of the first 3:

Top left red pushbutton: reads and activates the switches at the back. It also sends CC#120 (All sound off).
Top white pushbutton = Stop: MIDI sync: Stop
Bottom red pushbutton = Start: MIDI sync: Start
Bottom right white pushbutton = Tap: after tapping 4 times a new taptime is calculated. This new taptime will only be implemented after pressing Start once. So, while the MIdrum is running or not, you can tap 4 times to get the new tempo and press play once to update this new tempo.

Please.

Thank you and enjoy.
